• please ask pouet staff to add "neogeo" platform, so it can be the "first" neogeo demo :)

• tft: you're right, it's a musicdisk... I missed it when I added the demo. Maybe a "pouet" admin could change it.

• mic: you're almost right. 68k only send a "tick" command at 50hz (ATARI music are 50hz). Then Z80 wake up at 50hz, and depack YM registers (all data is packed in Z80 ROM, the packed music is about 43KB). And then the magic trick is that NeoGeo has a YM2160 chip, far better than ATARI YM2149. BUT, the YM2160 has a SSG part (simple sound generator), which is hardware compatible with YM2149 :) So no software emulation, I simply put the registers into the SSG par of the YM2160

• I guess some of you will be hurt by nasty graphics of this demo, and I agree :) This is "oldskool" demo so the only goal is to have technical tricks, and no nice graphics... Here are some details about the three technical tricks used here:
  
  1) A big spinning filled vector cube. NeoGeo can't do software rasterizer because graphics are only made of tiles, located in ROM (CPU can't modify tiles bitmap)
  
  2) The color bars are disting in Y axis, so it required sprites. There is 32 bars of 20 sprites each (NeoGeo sprite is ALWAYS 16 pixels width) wich means 640 sprites! But Neogeo only support 384 sprites!
  
  3) During the demo you're listening an ATARI-ST music! It's a ST-Sound YM music, my own ATARI sound emulator. I'm sure you never hear that kind of sound on your NeoGeo :)

• ggn: to bypass the mame crc check, juste run the game from command line
  
  mame puzzledp
  
  if a rom is specify, it bypass the crc check, so it runs perfectly on mame (but the sound is less accurate than a real hardware)

• Hi Folks
  
  This is the first NEO-GEO demo by Oxygene!
  
  Note: This demo runs on real hardware: MVS cartridge or NeoGeo CD
  (Thanks to Furrtek for testing it on real hardware)
  
  This package contains both ISO file for NeoGeoCD version, and
  classic ROM files to run on emulator or flash on real hardware.

• hitchhikr: yes I try "-t" switch. It almost work but with some files (even smaller than 64Kb) I get that error message: "Packing binary file... no tiny mode available for that file". Do you know how I can fix this?"
  
  fiveofive: the LZMA version is really better than any other packer (about 20%) but it's too slow to be used on a demo. The Tiny mode is very similar to standard atari packers such as speekpacker or Ice. A bit better than ARJ sometimes for small files.
  
  rez: no :-) I just update my ATARI demo toolchain. (available here: http://pouet.net/prod.php?which=56952 )

• Hi! Me again!
  Could you please add a "force tiny mode" option in the packer? In my case, for my ATARI-ST demo system, I use ARJ-7 or PAckFire to packe screens. PackFire "LZMA" is useless on ATARI because it's too slow. So when my toolchain pack binaries, I run ARJ and PackFire, and I select the best result for each binary. Unfortunatly, as the "LZMA" model is generally smaller, I never get a valid "tiny" packed file.
  Please add an option "force tiny packing, even if LZMA mode is smaller"
  Do you think it's possible?
